Application September 22, 1944, Serial No. 555,302

1 Claim. (01. 20- 56A),

This invention relates to certain new and useful improvements in window lights, panes and the like, and has more particular reference to a novel sheet or pane such as is adaptable for use in doors, windows and equivalent structures.

In the accompanying illustrative drawings, representing the preferred embodiment and adaptability of the invention, I have disclosed a window pane characterized by a ledge fiange, this being thenew feature and being located at the bottom and extending laterally outward in respect to the body portion and serving as a combined seal and ledge-like shed for the elements, whereby to coact with the customary putty seals or other sealing agents and to thus provide a pane which lends itself admirably well toward achieving the desired ends.

It is a matter of common knowledge that the ordinary or conventional window glass or pane is in the form of a rectangular or equivalent sheet whose marginal edges fit into rabbets provided therefor in the outer surface of a regular sash frame, the pane being held in place around its perimeter edges by means of putty or equivalent retaining and sealing elements, or agents. It is well known that putty generally fails first along the horizontal or lower reach. This is becaus it is subjected to the elements, the accumulation of dirt and thedirect rays of the sun. In due time these factors cause leakage of dirt, air and deterioration of the parts. The putty becomes rough and interferes with washing, and when frequently washed, chunks break off to ultimately render the retention and sealing functions ineffective.

It follows, therefore, that I have evolved and produced what is believed to be a more feasible and practicablewindow pane which is characterized by simplicity and durability, will render washing easier, painting quicker and more expedient, will modernize the appearance of the overall Sash and will accomplish results calculated to render this newer style pane more aptly fitted for the purposes intended.

Briefly, and as above mentioned, I achieve the aims desired by the simple provision of a right angularly disposed out-standing seating, sealing and retention flange, this located at the lower end of the pane, and being of appropriate dimensions and cross-sectional shape.

In some forms of the invention, where comparatively large panes are needed, the flange is provided with a longitudinal open-ended groove in its under side, this to function as a keyway and said keyway serving for reception of a bead,

or a putty packing strip to thus add greater stability and more effective retention properties.

Other features and advantages will become more readily apparent from the following description and the accompanying illustrative'draw- In the drawing, wherein like numerals are employed to designate like parts throughout the same: 7 I

. Figure 1 is a vertical sectional view of a double-sash window structure having panesconstructed in accordance with the principles of this invention; I I,

Figure 2 is aperspective view of the window pane per se, this to bring out the specific and preferred construction thereof.

Referring now to the drawing, and especially to Figure 1, the upper window sash is indicated at 3 and the lower sash at 4. The outer portion of the upper sash frame is fashioned with the customary rabbets 5 for reception of the window pane 6. As is customary, the rabbeted grooves extend around all four sides of the window opening. However in the lower sash the meeting rail of the sash frame is provided with a central groove 1, the other three sides being rabbeted the same as in Figure 1. The window pane, which is denoted by the numeral 8 is the phase of the invention in which I am primarily interested. It is understood that this part may be of regular glass, plastic glass, or in the form of any equivalent transparency. Thus, the material from which the window pane is made is immaterial, as it were. I am using the expression pane to cover any transparency for use in doors and windows. The body portion 9 is conventional. In fact, the only difference between this and other panes is the fact that the lower edge portion is provided with an outstanding integral right angularly disposed flange l0 whose under side is flat to fit snugly in the rabbet and whose upper side H is tapered, the outer marginal edge [2 being suitably shaped, preferably somewhat rounded. Thus, in cross section, the flange resembles a regular run or stretch of putty.

The upper pane is fitted into the sash 3 and held'by the customary exterior putty seals [3, these being arranged around the upper edge and the two vertical edges. There is, however, no exterior putty seal or run at the bottom, since the flange l2 takes the place of the putty which would otherwise fill and occupy this region of the rabbet. Therefore, it is evident that the only structhe sealing and retaining flange I0.

In Figure 2, the upper edge of the pane is fitted into the groove or channel I and the vertical or perpendicular edges are retained in place by the customary putty runs or seals [4. Thus, in this adaptation there are two putty runs, the upper end of the pane being seated in the groove and the lower end being provided with the aforementioned flange.

In certain forms of the invention I have found it exceedingly practicable to provide the under flat side of the flange with a longitudinally extending groove l 5 which constitutes a keyway this to accommodate either a special rigid bead, or a bead l6 fashioned from putty. It is understood that the features l5 and it are optional and are enerally used in only large window and door openings.

It is to be understood that the novelty, as defined by the sub-joined claim, has to do with the window frame in combination with the specially flanged window pane or panel. However, the essential novelty is directed to the construction of the panel or pane itself, particularly the unique flange possessed of water-shedding and retention properties; The expression putty has been used here and there merely to define suitable seals or retaining elements for the nonflanged edges of the window pane. In certain constructions putty is used both around the exterioredge portionsof the window, pane and also vback putty is used in the rabbet or groove, that is, between the panel and surfaces of the rabbet. I desire the breadth and scope of the claim interpreted with these qualifying factors in mind.

A careful consideration of the foregoing description in conjunction with the invention as illustrated in the drawings will enable the reader to obtain a clear understanding and impression of the alleged features of merit and novelty suflicient to clarify the construction of the invention as hereinafter claimed.

Minor changes in shape, size, materials and arrangement of parts may be resorted to in actual practice so long as nofldeparture is made from the invention as claimed."

I claim:

In a sash construction, a frame having a marginal ra bbet, a flat sheet window pane fitted r therein and held around the upper end by putty,

along both vertical edges by putty, and having an adaptable holding and ledge forming flange solely at its lpwer end extending horizontally and seating on the adjacent surface provided by the coacting region of said rabbet.
